PLOW.

SPECIFICATION forming part of Letters Patent No. 360,586, dated April 5,1887.

Application filed August 20, 1856. Serial No. 211,382.

, nois, haveinvented certain new, and useful Improvements in Plows; andI do hereby declare vthat the following is a full, clear, and exactdescription ofthe same, reference being had to the annexed drawings,making a part of this speciication, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a perspective view of my invention; Fig. 2,an under side perspective View showing the manner of bracing the handlesto the plow; Fig. 3, a detail view in elevation of the forward end ofthe plowbeam, showing the colter connected thereto; Fig. 4, a transversesection thereof; Fig. 5, a sectional elevation taken on line y y of Fig.3, and Fig. 6 a longitudinal section through the forward or draft end ofthe plowbeam.

The present invention has relation to that class of plows provided withadjustable beams, also adjustable colters, and is especially designed asan improvement upon my former patent, bearing date February 6, 1883, No.271,844, and the object thereof is to improve this class of plows in theseveraldetails of construction, as willbe hereinafter described andclaimed.

In the accompanying drawings, A represents the plow,provided with astandard, I3, which has a downwardly-extendingbraceplate, C, of

sufficient size to fill up all space between moldboard and landside,thereby avoiding clogging, which would result from open space being leftbetween standard, mold-board, and landside of the plow. rIhe standard Bis formed in one piece'with a brace, D, said brace extending up alongthe outer side of one of the handles and suitably bolted thereto, thusgreatly strengthening the handle where most needed, and, the standardand brace being formed in one piece, there is no danger of the latterworking loose therefrom, while the cost 'of manufacture is greatlydiminished.

The plow-beam E is pivoted by bolt a to a bifurcated hanger, F, saidhanger supporting the plow and enabling it to turn laterally in eitherdirection. This hanger F,near its lower end,has curved slots b, throughwhich passes (No model.)

a set-bolt, c, provided with a nut, d, engaging with the screwthreadedend thereof, said bolt also passing through the standard B. The hanger Fis also pivoted to the standard B immediately above the set-bolt, asshown at c, thereby forming a very simple, strong, and durableconnection between the plow-beam and standard, and enabling the beam atits forward end to be adj usted as to height by means of the set-boltand slot hereinbefore described.

The plow-beam, which is preferably made of malleableiron,iscomparatively straight,there by giving a straight draft, and has at itsforward end a swiveled clevis, G, thereby keeping the double-trees inproper position should the plow upset on either side or be tipped inturning. In addition to the brace D, which is connected to the haudle'H,a brace, I, is employed, which is bolted totheinnerside ofthe handleJ,and also to the inner side of the moldboard of the plow, therebystrengthening the handle J in the same manner as brace D does the handleH, this latter-mentioned brace ob viating the necessity of twisting thelowerend of'the wooden handles by steam, which is an expensive process,by reason of a considerable percentage of the handles being broken whilebeing thus twisted.

As a substitute for the ordinary wooden braces between the plow-handles,I provide metal braces f g, bolted to the handles and together in anywell-known manner, the metal not being affected by moisture, as in thecase of wooden braces. rIhe rear end of the plowbeam E has a transverseslotted plate, 71, through which passes a suitable clampingscrew, fi,said screw connecting to the under side of the plate slotted andserrated hangers K, said hangers being capable of vertical adjustmentand held in their adjusted position by means of a set screw or bolt, k,and a serrated clamp, Z, the serrated face thereof engaging with theserrations upon the outer side of one of the hangers K, the serrations,as should be understood, being on one of the hangers only, and the setscrew or bolt 7c passing through the slots in the hangers and alsothrough the brace D and plow-handle H. By this construction a verysimple and effective means is provided for raising or lowering the rearend of the plow-beam, the slotted plate 71 and setscrew z' enabling therear end of the ICO beam to be adjusted laterally, said adjustmentsbeing required to bring the forward or draft end of the beam in theposition required.

The wheel-colter Lis provided with a square opening, through whichpasses a correspondingly-formed hub, m, projecting from the inner sideof a clamping-disk, M, the hub having an extension, n, also formedsquare in cross-section, and over which fits a clampingdisk, N. Betweenthese disks are held the colters by means of a bolt, o, which passesthrough the disk and colter, and is provided with tightening nut p,engaging with the screw-threaded end of said bolt, as shown in Fig. 6.This bolt o also connects to the colter and clamping-disks arms O P,which are so constructed at their lower ends as to form caps q, whichfit over flanges r upon the outer side of the clamping-disks, therebyforming a solid and firm bearing for the clamping-disks to revolve in,the disks carrying with them the colter. By this construction thefastening-bolts ordinarily used are dispensed with, thus avoiding thewear of the colter revolving on the bolt and thev consequent wearing andcutting of the bolt and the enlargement of the oolter-hole by frictionalwear. These objections are all obviated by the constructionY hereindescribed, while the colter will run truer without lateral play.

The employment of the caps q, which fit over the rims or fianges a,excludes all dirt and foreign substances therefrom.

The arms O l? are curved out, as shown ats, to form scrapers to cleanthe sides of the colter from earth, grass, &c., that may adhere thereto,the scraping edges upon the arms being formed in any well-known manner.The arm P is detachably connected to arm O by means of a bolt and nut,or any other well-known means may be employed to attain this end, andthe arm O is formed at its upper extremity with a sleeve, Q, which iitsover a pin, t, depending from a head, It, the sleeve being held to thepin by means of a'set-screw, u, passing through an elongated slot,v, andengaging with a screwthreaded hole in the pin, thereby forming aswiveled connection between the colter-arms and plow-beam. The head R ofthe pin tis provided with a screw-threaded hole, through which passes ascrew-rod, S, said rod having its bearings in a right-angle plate, T,which plate is connected to the forward end of the plow-beam. By turningthe screw S, by means of a wrenchV or other suitable tool, the head R ismade to travel longitudinally thereon, the head extending down throughan elongated slot, w, which admits of its movement and forms a guide forthe same. The plate T is vertically adjustable by means ofthe bolt andnut a b', the bolt passing through an elongated slot, c', and throughplates d and e', the plate e being connected to a slotted plate, f', bybolts g and nuts h', which are also rmly secured to the plow-beam E. Theupright portion of the angle-plate T, in which the slot c' is formed, isseated between flanges fi', formed on a plate, U, said plate havingslotted ends k', through which pass bolts Z, provided with screw-nutsm', these slots in the several plates and the screw bolts and nutsadmitting of the various adjustments of the colter, as circumstancesrequire.

The means herein described for connecting the wheel-colter to theplow-beam is equally applicable to any of the plow-beams now in ordinaryuse, whether of metal or wood, and obviates the use of bolts or rivetsthrough the plow-beam.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

l. In a plow, the beam, the standard B, formed with extendingbrace-plate C, and brace D, in combination with braces I and braces f g,formed of metal and connected to the plow-handles, substantially as andfor the purpose set forth.

2. In a plow, the combination, with a pivoted beam thereof, having atits rear end a transverse slotted plate, h, of the independentvertically-adjustable slotted hangers K, connected to the plate of thebeam by clampingscrew i, one of said hangers having a serrated face anda serrated clamp engaging therewith, and bolt for holding said clamptothe hanger, substantially as and for the purpose set forth.

@3. In a plow, the wheel-eolter thereof, having a square openingthrough-its axis, in combination with the clamping-disks M N, said diskshaving flanges or rims 1, and arms O I?, having caps q,iitting over theflanges, and a bolt and nut for holding the parts together,substantially as and for the purpose specified.

4. In aplow, the combination,with a wheelcolter, ot' arm O, having anindependent section, I), bolted thereto, said arm and section beingprovided with scraping-edges on their inner sides, substantially as andfor the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

CHARLES I-IANSON.
